Unless the jin is doing 6B from 6C I usually refrain from mashing because of the foot invuln. (Not good at 6A it with terumi, especially since i am out of practice.) Like terumi's 6B, you gotta remember that's a lot of booty you're going to give up if you mess up.
P.S. I know 5As work too but i'm still afraid of the risks most of the time since i don't have the timing down 100%
